When buying a used excavator, making the right choice requires careful inspection and research. Here are 10 essential tips to help you select a reliable machine:
- Check Overall Condition: Inspect the body for cracks, welds, or rust. Uneven paint may indicate repairs after accidents. Check the undercarriage—tracks, rollers, and sprockets should have minimal wear.
- Engine Performance: Start the engine to listen for unusual noises. Observe exhaust color: blue smoke means oil burning, white smoke indicates coolant issues, and black smoke suggests fuel problems.
- Hydraulic System Test: Operate all hydraulic functions. Slow or jerky movements may signal leaks or pump damage. Check hoses and cylinders for leaks or bulges.
- Maintenance Records: Ask for service logs. Regular maintenance, like oil changes and filter replacements, shows the machine was well-cared for. Missing records are red flags.
- Hours of Operation: Lower hours don’t always mean better condition, but combine this with maintenance history. A 5,000-hour machine with proper upkeep is better than a 3,000-hour neglected one.
- Model Reputation: Choose models known for durability, such as Kubota U35, Cat 320D, or Hitachi ZX135. These have widespread parts availability and strong resale value.
- Purpose Match: Pick a size and features for your needs. Compact models like Kubota U35 suit tight spaces, while larger ones like Volvo 480D handle heavy-duty tasks.
- Document Verification: Ensure clear ownership documents to avoid legal issues. Check for liens or outstanding loans on the machine.
- Professional Inspection: Hire a certified mechanic to assess critical components. Their expertise can uncover hidden problems you might miss.
- Test Operation: Take the excavator for a test run. Evaluate its responsiveness, stability, and performance in real working conditions.
Q&A
Q: Is it worth buying a used excavator with over 10,000 operating hours?
A: It depends on maintenance. A well-maintained 10,000-hour machine can still be reliable, especially if major components like the engine and hydraulic system have been serviced regularly. Always pair hour count with inspection results.
Q: How can I verify the accuracy of the excavator's hour meter?
A: Cross-check with maintenance records, as service entries often note hours. Also, inspect wear on controls and pedals—excessive wear with low hours may indicate tampering. A mechanic can check for meter adjustments.
A quality used excavator offers cost savings without sacrificing functionality. It should have consistent performance, compatible parts, and a history of reliable operation—key advantages for your projects.
By following these tips, you’ll be well-equipped to choose a Used Cat Excavator or Hitachi ZX70 that delivers reliability, efficiency, and value for your projects.
